Back when the Quarter Horse Association came about and decided to exclude the piebald coat that the American Paint Horse is renowned for, a few individuals got together to start their own Paint Horse enthusiast clubs. Over the years and after much organization, the various clubs pulled together and formed the America Paint Horse Association. Its numbers grew quite steadily until the APHA found itself the second largest breed registry in the United States. The organization has many corporate sponsors, numerous regional branches and a large membership base over one hundred thousand strong. It has been shown that the American Paint has enthusiasts from all walks of life and that their loyalty to the breed is strong.

The APHA strives to uphold and advocate on the American Paint's behalf. Not only do they register Paint Horses, they also educate the public and hold many events to create awareness of equine related issues. Through the organization one can locate breeders, trainers and even learn about their non profit foundation that works to maintain the breed's extensive heritage. The APHA also has three magazine publications plus a yearly directory of reputable breeders and trainers located throughout the United States. One can also access information via the organization's website. The onsite headquarters for the APHA are located in Ft. Worth, Texas.

Another organization that combines two areas that are wonderfully apt is the AJPHA, or the American Junior Paint Horse Association. The American Junior Paint Horse Association offers youth an outlet to involve themselves in the care and advocacy of the American Paint at their very own level. The organization offers youth programs and events that welcome children of all age ranges. Activities that consist of everything from showing to riding are available through the program and children can earn prizes and various awards for their participation. Children can not only work with their horses, they can participate in service projects that help promote the American Paint. Regional clubs are found nationwide.

There are many organizations outside of the United States for American Paint enthusiasts. One of these organizations is the Alberta Paint Horse Club. Through the APHC, residents throughout Alberta, Canada have the chance to appreciate the American Paint with others by participating in various events and competitions. Members of the club have a valuable resource in which to locate a number of breeders, handlers and other services that deal with or relate to the American Paint Horse. The club offers not only programs and incentives to adult members but to the organization's youth group as well. Young riders and handlers can now get involved with their favorite breed and reap the rewards of learning good horsemanship.

Another similar organization is the Ontario Paint Horse Club. The OPHC is an organization for American Paint Horse enthusiasts in Ontario, Canada. The club came into existence in 1970, barely a decade after the American Paint Horse Association was established. The OPHC steadily works to bring American Paint enthusiasts together while promoting high moral character and sportsmanship.
